KATHON FP 1.5 (tm)Kathon is world’s leading broad-spectrum preservative and Disinfectant for treatment of diesel, aviation, kerosene and heating fuels.

Supplied in 5kg and 20kg pails. Used by aviation, shipping and major companies globally for preservation and safe protection against contamination by microbial growth.

Kathon FP1.5 is a broad spectrum preservative and disinfectant for the treatment of diesel fuels, kerosenes, heating oils and aviation fuels, the active components being isothiazolone compounds.

General Application Kathon FP1.5 is normally dosed at the rate of approximately 300 ppm, which corresponds to 0.3 kg per 1000 litres of fuel volume. If Kathon FP1.5 is being dosed as a precautionary measure, or when there is a low level of microbial contamination, a lower dosage rate of approximately 150 ppm (0.15 kg per 1000 litres) will be appropriate. In cases of severe contamination, however, a dosage rate of up to 1000 ppm (1.0 kg per 1000 litres) should be used.

Aviation ApplicationA dose rate of 100ppm with a minimum retention time of 12 hours should be used in JET A1 fuel and all other aviation applications. Where possible, water and sludge should be removed from fuel tanks before and after dosing Kathon FP 1.5. If this is not feasable, filters should be checked more frequently for a short period, due to microbial slimes being killed off, broken up and dislodged.

Ideally, Kathon FP1.5 should be dosed shortly before the tank is re-filled with fresh fuel. The resulting agitation of the fuel then ensures uniform mixing of the biocide throughout the tank. Kathon FP1.5 can be added directly to the tank in such cases. If dosing cannot be carried out shortly before a fuel delivery, it is preferable to dissolve the Kathon FP1.5 in a small quantity of fuel, then add the solution to the tank.

Depending upon site circumstances, it may sometimes be necessary to neutralise residual biocide before discharging treated water bottoms to the foul drain.
